Pokémon Go region exclusives tie a handful of the first three Generations to specific locations around the globe.

Gen 1's Tauros, Kangaskhan, Mr. Mime and Farfetch'd, Gen 2's Heracross and Corsola, and Gen 3's Zangoose, Seviper, Lunatone, Solrock, Illumise, Volbeat, Tropius and Relicanth are creatures in question, which are all region-locked to specific locations, making them among the rarest in Pokémon Go.

Over a year after release and, by and large, the creatures have remained locked to their specific regions, except in a handful of special events. So unless you travel a lot, if you're patient you might have the chance to catch something you'll never find on your shores.

How region exclusives in Pokémon Go work

Each generation of Pokémon has several creatures you can only find in specific regions. These can be specific countries (such as New Zealand's Relicanth), entire continents (Europe's Mr. Mime), certain regions (Corsola in the Tropics) and even 'halves' of the planet (such as Lunatone and Solrock).

There are more specifics on where to find every creature below, but at a glance, here is where every region exclusive can be found, courtesy of jdave512 on reddit:

These creatures are fairly common spawns in these regions, so if you are visiting for a short period, it won't take long to find them. Finding them out in the wild is the only way, though - they cannot be hatched in Eggs, found in nests or spawn in gyms.

If you don't travel, then don't fret. Gen 3 has shown these creatures can swap round frequently (such as Zangoose and Seviper) or drop region exclusivity altogether (Plusle and Minun) and as mentioned above, shift temporarily for special events, such as Farfetch'd during Pokémon Go's 2017 Travel Challenge.

How to catch the four Gen 1 region exclusives in Pokémon Go:

Pokémon

Region

Type

Encounter Locations

Notes

Tauros (Gen 1)

North America

Normal

Generally everywhere, some reports of it appearing in expansive, desert-like or rodeo-related areas

The general word is that this includes all of North America, but whether or not it appears in South American countries is still up for debate.

Kangaskhan (Gen 1)

Australasia

Normal

Generally everywhere, with reports indicating it's appearing in cities and parks in particular

There's some debate here over whether Kangaskhan is exclusive to just Australia, or Australasia as a whole, with some differing anecdotal chatter from people in New Zealand.

Mr. Mime (Gen 1)

Europe

Psychic/Fairy

Generally everywhere, including city centres like London

Yes, the UK still counts as being in Europe; we voted out of the EU, not the continent.

Farfetch'd (Gen 1)

Asia

Normal/Flying

Generally everywhere, being a normal type. Reports of Farfetch'd appearing in city centres and parks in particular, likely due to its part Flying typing.

Japan and South Korea seem to be particularly abundant places. There are some pretty large numbers of people reporting Farfetch'd appearing en masse in Japan since their servers went live.

Heracross (Gen 2)

Generally everywhere.

Though it's described as Latin America region exclusive, many reports of southern parts of Florida and Texas have also reported sightings.

Corsola (Gen 2)

Tropics

Psychic/Fairy

More common in water areas between the two Tropics.

Early research suggests between 31N and 26S. In short this includes - but not all parts of - south Florida, Latin America, Africa, Asia and Australia and more.

*As an interesting lore tidbit, Zangoose and Seviper are natural enemies (like a mongoose and a snake...) and so are never on the same continent. They actually started in reverse of the continents above, but swapped at the end of the Winter 2017 event, so they may swap back again!
